When I try to synchronize a folder that has some image files added, LR searches for new files and find some, then when I click the Synchronize button loads the "From - To" window with no thumbnails showing, and then just hangs there. If I check the Task Manager, LR is using about 12% of CPU. It will stay that way indefinitely.
I have optimized the database, restarted, rebooted, removed and reinstalled LR. Nothing seems to help. I can import files with no difficulty.
Anybody else seeing this problem? Any way to fix it?
